One day an eight-year-old boy went to the pet store with his dad to buy a puppy. The store manager showed them to a pen where five little furry balls huddled together.
After a while, the boy noticed one of the litter all by itself in an adjacent pen.
The boy asked, "why is that puppy all alone?"
The manager explained, "That puppy was born with a bad leg and would be crippled for life, so we're going to have to put him to sleep."
"Your going to kill this little puppy?" the boy said sadly while patting it.
"You have to realize that this puppy would never be able to run and play with a boy like you." the manager explained.
After a short conversation with his boy, the dad told the manager that they wanted to buy the puppy with the bad leg.
"For the same amount of money, you could have one of the 'healthy' ones. Why do you want this one?"
To answer the manager's question, the boy bent over and pulled up the pants on his right leg, exposed the brace underneath and said, "Mister, I want this one because I understand what he's going through."
